Official start of Gaarkeuken wastewater treatment plant renovation

On Wednesday, July 17, 2024, the water authority will celebrate water authority official start of the construction and renovation of the sewage treatment plant (STP) at Gaarkeuken.

Multi-million investment 

The work has already started a little earlier. Nevertheless, after years of preparation and planning, the water authority wants to pause water authority a moment water authority this point. Administrators, the contractor, and local residents will be present at the celebration. 
In October, we already started laying new pressure pipes between Marum and Zuidhorn. These pipes will transport the wastewater to the renovated treatment plant in Gaarkeuken. Once the construction and renovation of Gaarkeuken is complete, these pipes can be connected. 

The renovation of the treatment plant requires an investment of €27.3 million. The construction of the pressure pipes for transporting the wastewater to the new treatment plant will cost €28.5 million. Together with all the preparations and planning, the investment for securing treated in the Westerkwartier amounts to almost €67 million.

One new treatment plant

The old sewage treatment plants in Marum, Zuidhorn, and Gaarkeuken are outdated. Therefore, a new treatment plant will be built in Gaarkeuken. Gaarkeuken will become the central treatment plant, taking over the functions of the other locations. The locations in Marum and Zuidhorn will eventually close.

New information center

In addition to the official start of construction and renovation, a new information center will also be opened at the Gaarkeuken site. This center is specifically for school classes and interested parties from the surrounding area. The center shows what the water authority and provides information about the construction and renovation work at the Gaarkeuken wastewater treatment plant. It also explains what is contained in sewage water.
